What are induction hobs and how do they work?
Induction hobs are a type of cooking surface that uses electromagnetic fields to generate heat directly in the cookware. Unlike traditional gas or electric stoves that heat the cooking surface, induction hobs heat the cookware itself, which in turn cooks the food inside. This efficient process offers precise temperature control and quick cooking times, making them a popular choice among both amateur and professional chefs.
The way induction hobs work is by using copper coils beneath the glass surface. When an induction-compatible pot or pan is placed on the hob, the electromagnetic field created by the coils induces an electric current in the cookware. This current produces heat that is then transferred to the food. One of the main benefits of this system is that the hob remains relatively cool to the touch, reducing the risk of burns or kitchen accidents.
Are induction hobs safe to use?
Yes, induction hobs are generally considered safe for use. They operate using electromagnetic fields, which are well within the safety standards set by health organizations.
